I NECK-YOKE STOP.

Application filed. June 20, 1911.

To all whom it may concern Be it known that I, WILLIAM KNIGHT, a citizenof the United States, residing at Hill, in the county of Chouteau andState of Montana, have invented certain new and useful Improvements inNeck-Yoke Stops, of which the following is a specification.

My invention relates to improvements in neck-yoke stops and has for itsleading object the provision of an improved attachment for the tongue orpole of a wagon which will allow the engagement of the neckyoke centeron the end of the wagon tongue or pole and will prevent the accidentalslipping of the neck yoke center off of the pole or tongue.

A further object of my invention is the provision of a simple andefficient device of inexpensive construction which shall be made in suchform that it may be readily secured in position in the end of a wagontongue or pole and will be entirely complete without the addition ofsupplemental parts.

Another object of the invent-ion is the provision of a device comprisinga combined securing sleeve guide member which may be readily insertedand secured in a socket formed in a wagon pole or tongue, which memberwill contain a. locking pin for preventing the accidental slipping ofthe neck yoke center, and will further contain a spring for normallyforcing the pin outward 'lito position to engage the neck yoke center.

Other objects and advantages of my improved neck yoke stop will beapparent from the following description taken in connection with theaccompanying drawings, and it will be understood that I may make anymodifications in the specific structure shown and described within thescope of my claim without departing from or exceeding the spirit of theinvention.

Figure 1 represents a view of my device applied to the pole of a wagon.Fig. 2 represents a longitudinal sectional view thereof. Fig. 8represents a side elevation of the device removed from the pole, andFig. 4: represents a detailed view of the locking pin.

In the drawings, the numeral 1 designates the pole of the wagon havingthe usual abut ment 2 to limit the movement of the neck yoke center 8,while secured to the pole a short distance nearer the end of the polethan said abutment 2 is my improved device. Said device comprises asleeve 4 having an inwardly flanged end 5 and being providedSpecification of Letters Patent.

with the threads 6 adjacent said inwardly flanged end, while secured onthe other end of the sleeve is the angular plate 7 to facilitate theturning of the sleeve, the threads 6 engaging the face of a socketformed in the tongue to facilitate the screwing of the sleeve up intoposition in the pole or tongue 1. Slidably mounted within said sleeve 4;is the locking pin 8 having a reduced inner end 9 around which is woundthe helical spring 10 having one end bearing against the shoulder 11 ofthe pin and the other against the inwardly flanged portion 5 of thesleeve, the spring thus tending to force the pin out of the sleeve. Toboth guide and limit the movement of the pin in the sleeve, I form indiametrically opposite sides of the sleeve the longitudinal slots 12,while passing through the pin below or exterior to the shoulder 11 isthe securing bar or pin 13 which has its ends projecting outward fromthe stop and slidably engaged in the slots 12,

the contact of said member 13 with the ends of the slots 12 limitingboth the inward and outward movements of the stop pin 8.

From the foregoing description taken in connection with the accompanyingdrawings the construction of my improved stop will be readilyunderstood, and it will be seen that it is merely necessary to form asocket in the under side of the wagon pole ortongue and then by graspingthe angular plate 7 to turn the sleeve, when the threads will engage theinterior of the socket and draw and hold the sleeve up therein. To placethe neck yoke center in posit-ion or to remove the same it is merelynecessary to press the stop 8 inward against the tension of the spring10 until the center has been passed thereover, when upon the releasingof the stop the spring will force the same outward to limit the movementof the neck yoke center.

I claim:

In combination with a wagon pole having a socket formed therein, of aneck yoke stop comprising a sleeve having an angular head formed on oneend and adapted to bear against the undersurface of the pole adjacentthe open end of the socket, said sleeve having the other end inwardlyflanged and exteriorly threaded for engaging the socket to retain thesame in place, said sleeve haw ing longitudinally extending slots formedin the intermediate portion of diametrically opposite sides thereof, astop pin slidingly mounted in the sleeve and formed with a reducedshouldered end, a helical spring fitting around the reduced end of thestop and having one end bearing against the shoulder stop, and the otherend bearing against the inwardly flanged portion of the sleeve, and across pin passing through the stop below the shoulder thereof and havingits ends projecting into the slots of the sleeve, said ends beingshorter than the Width of the slots to prevent contact With the Walls ofthe socket,

the ends of the slots serving to limit the movement of the cross pin andthus of the stop.

In testimony whereof I aflix my signature, in the presence of tWoWitnesses.

WILLIAM KNIGHT.
